Allinea DDT Training

The secret to successful debugging is in the methods and in the tools that are used.

We teach the art and the science in debugging with real examples and hands on material. Adding process to debugging and using and understanding the right tools for the problem can make the difference between rapid success and frustrating failure.

We show the easiest ways to get to the bottom of complex problems using Allinea DDT, and develop methods that make problems disappear quickly.

You will learn quickly how to track down suspected memory problems or random application crashes on even the largest parallel or GPU codes.
